ln the accompanying drawings, Figure 1 is an elevation of the harmonica; Fig. 2, a longitudinal section on line Q Q, Fig. 1; Fig. 3, a crosssection on line R R, Fig. 2, with the valve A closed; Fig. 4, a similar section With the valve A open, and Fig. 5 a sectional plan of the cells.

The harmonica K is provided, in addition to the reed-plates f f', with a further reedplate g. This plate is located over the aircells 71, of an extension D of harmonica K.

If closed, the valve A Will cover the air-openings of plate g, and therefore such plate will not be sounded; but when the valve is opened the plate g Will sound in addition to the plates ff. Thus the volume of tone may be regu- CARL ESSBACl-l,
